> This has caught systems which have a race condition where you can move your mouse quickly and gain desktop access before it locks.

I fail to see how this is a race condition rather than how a screensaver is supposed to work?






Because it’s not, that’s why I pointed to xscreensaver feature implementation. Lock time is separate from screensaver activation time which is separate from energy saving activation time.

What defines when a locking screen saver is “locked”? 10m? Or 10m1s? You are making assumptions and that is what DISA spells out. Which forces the OS design to change in subtle ways. Like xattrs on files as great grand op was alluding to.

Does that provide clarity into how development security models evolve over the lifetime of an application?
